What is a lava cameo?

How are Victorian gold standards told apart?

Victorian jewellery utilises various gold purities, including nine carat, fifteen carat and eighteen carat. Hallmarks and specific colour tones help distinguish the alloy content. Lower carat metals contain higher proportions of base alloys, altering the yellow or rose hue of the mount.
